PAUL, MINNESOTA, A CORPORATION OF MINNESOTAFOUNTAIN PEN Application filed February Our invention relates tofountain pens wherein it is desired to provide means for operating theink sack to collapse the same when it is desired to expel the air or theink in the sack. V

A feature of the invent-ion is an extremely simple, inexpensiveconstruction with only two operating parts, namely the lever and the inkengaging or compressing bar.- These two parts operate in a mannerso asto force the ink sack into a collapsed state when the lever is raised,and to permit the sack to expand when the bar is elevated by loweringthe lever.

It is also a feature of the invention to provide means forsupporting thelever directly by the casing of the fountain pen which may be made ofmetal or any other suitable material. By a particular construction, yet

simple, we look the lever against disengagement from the casing orbarrel of the fountain pen when it is in operating position. It is onlypossible to remove the lever when the same is rotated into aninoperative position insofar as the bar is concerned and over far enoughso as to release it from the casing.

This can only be accomplished when the ink sack presser bar is removedor disengaged from the operating lever.

Our invention also includes a lever adapted to carry and lift the inkpresser bar, including means 'engageable over the operating end of thelever to lock the lever and bar together againstfree disengagement, butpermitting the same to be-separated, if it is desired, thus forming acatch with the inner operating end of the lever and. the sack presserbar. This construction provides means for preventing the presser barfrom slipping out of the barrel when the'ink sack and pen point areremoved' Yet the presser bar can be released from the leverby engagingthe same and pulling it sufliciently to release the catch.

These features, together with other objects and particular form ofconstruction of our fountain pen will be more fully and clearly setforth in the specification and claims.

In the drawing our fountain pen A is adaptthe line 77 of ed to beprovided with a writing nib 10, held in the ordinary manner in thesection 11, which is provided with the shank 12 and to which is securedthe ink sack 13.

The fountain pen A is designed to receive a largeink sack 13 and isconstructed with a metallic shell or barrel 14, which is attached to theshank 12 in a manner to hold the barrel 14 rigidly secured to thesection 11. The barrel 14 forms a cover for the ink sack 13 and for thelever operating mechanism B, which is adapted to press the sack so thatit can be filled with ink.

The lever operating mechanism B includes the finger lever 15 which isformed with an operating end 16, locking fingers 17 which are adapted toengage the barrel 14: to hold the lever in inoperative positionor-closed against the barrel.

The operating end 18 ofthe lever 15 is formed with outwardlyprojectinglugs 19 which are adapted to engagein the channels 20 formed in the inkpresser bar 21. The engagement of the lugs 19 inthe channel20 causes thepresser bar 21 to be lift-ed'orlowered as the lever 15v is operated, asillustrated in Figure 2. Depressions 22 are formed in the flanges whichform-the channels 20 of the presser bar 21 which formstops so as tolimit the movement of the presser bar 20 on the lugs 19. The lugs 19are'adapted to engage in the channels 20 freely so that the presser bar21 can be slid onto the lugs 19 when the lever 15 is pivotally attachedto the barrel 14. The construction of the presser bar 21 is i such thatthe spring of the material will permit the lugs 19 to be snapped beneaththe depressions 22 at one end so that the presser bar 21 is lockedagainst freely sliding back and forth on the lugs 19, when it is inoperation, between the limits of the stops or depressions 22. An opening23 permits the presser bar 21 to be engaged by a Wire or other suitablemeans so that it can be pulled sufficiently to release it from the lugs19, permitting the lugs to pass beneath the depressions 22.

The lever 15 is formed with a pivot opening 24 which is adapted toengage the bar 25 formed integral with the barrel 14- and extendingacross the lever slot 26. The lever 15 is adapted to be locked to thepivot bar 25 so that it will not become disengaged there from inoperation. To release the lever 15 from the pivot 25 it is necessary torotate it into the position illustrated in Figure 4, after the presserbar 21 has been disengaged from the lugs 19. The lever 15 cannot beremoved from the presser bar until the same is disengaged from the lugs19. When the lever 15 is rotated into the position illustrated in Figure4 the slots 28, which extend from the edge of the lever to the pivotopening 24 and which are of approximately the width of the pivot bar 25,permit the lever 15to he slid over the bar 25 or disengaged therefrom.In attaching the lever 15 it is slid onto the bar 25 through the slots28 to position the lever as illustrated in Figure 4 and then the leveris rotated so that the operating end 16 will lie with the spring fingers17 engaging the sides of the slot 26 adjacent the recess 29 which isadapted to receive the fiat end 30 of the lever 15.

A feature of primary importance in our invention resides in thesimplicity of construction, the small number of parts and the effectiveoperation of the lever and ink sack compressing means. In our fountainpen it is desirable to employ an ink sack with sufficient firmness andof a suitable thickness to the Wall of the sack so that a goodsubstantial ink sack is provided having long wearing qualities and beingadapted to readily expand in position to draw a large quantity of inkinto the same. No spring means is employed for lifting the presser bar21 from the sack but the particular construction is so designed andarranged as to cause the bar to be lifted away from the ink sack andheld up against the inner surface of the barrel H when the lever 15 isoperated to elevate the bar 21, thereby permitting the ink sack to fullyexpand and receive a substantial quantity of ink. The spring fingers 17engage the sides of the slots 26 in the barrel so as to hold the samelocked out of operating position. In this position the lever holds thepresser bar 21 locked in elevated position away from the ink sack 13.The presser bar may be made with or Without the indentations 22 and whenthe bar is held locked up against the inner surface of the barrel by thelever 15 it is held against sliding within the fountain pen. Then thelever is released and moved into operating position then the bar 21 maybe freely disengaged from the lugs 19. lVith the metallic barrel of ourfountain pen only two operating parts, outside of the barrel, areemployed, thereby providing a 10st simple, yet very effective fountainpen construction.

lVhile we have illustrated a particular form and construction of ourfountain pen in the drawing wedesire to have it understood that the sameis only suggestive of a means of carrying out our invention and that theparticular construction may be varied and applied to uses other thanthose above set forth, within the scope of the following claims.
